The Great Lakes, located on the border between the United States and Canada, are rightfully considered one of the most mysterious and inexplicable places on the planet. Seemingly calm, almost sea-like in scale, they conceal beneath their surface a power capable of instilling primal fear even in modern humans. Violent storms suddenly arise here, gigantic waves appear and disappear, and more than six thousand sunken ships lie buried on the seabed.

The submarine lay at the bottom of the icy Arctic Sea for a whole year before a brave team of Dutch engineers raised the wreckage of the cruiser and the bodies of the dead submariners were finally returned to their homeland.
